NetLinx Programming Overview

NetLinx Programming Language Reference Guide
The actual instancing of the structure is unique to the DEV structure because you separate the individual
structure's elements with colons (:) instead of enclosing the structure with braces
{} and separating the
elements with commas (
,). For example:
DEV PANEL_A = 128:1:0 (* correct *)
DEV PANEL_B = {128, 1, 0} (* wrong *)
Using the DEV structure, you create the structures DEVCHAN and DEVLEV like this:
STRUCTURE DEVCHAN
{
DEV DEVICE
INTEGER CHANNEL
}
STRUCTURE DEVLEV
{
DEV DEVICE
INTEGER LEVEL
}
DEVCHAN and DEVLEV instance and initialize similarly to other NetLinx structures:
DEV PANEL_A = 192:1:0
DEV PANEL_B = 129:1:0
DEVCHAN BUTTON_A = { PANEL_A, 1 }
DEVCHAN BUTTON_B = { 128:1:0, 2 }
DEVLEV LEVEL_1 = { PANEL_A, 1 }
DEVLEV LEVEL_2 = { 128:1:0, 2 }
DEV, DEVCHAN, and DEVLEV are structures built into the NetLinx language. You can do more with DEV,
DEVCHAN, and DEVLEV than you could with structures you create within the code.
DEV PANEL_GROUP1[] = { 128:1:0, 129:1:0, 130:1:0 }
DEV MSP_GROUP[5] = { MSP1, MSP2, MSP3 }
DEVCHAN PRESET1_BUTTONS[5] = { {TP1, 21}, {MSP1, 1}, {134:1:0, 1} }
DEVLEV VOL1_LEVEL[] = { {TP1, 1}, {MSP1, 1}, {192:1:0, 1} }
You can use the structures and arrays of the structures within many commands and situations where you
would use a device number, a device and channel combination, or a device and level combination. These
data sets allow you to combine devices, devices and channels, and devices and levels without using the
DEFINE_COMBINE or DEFINE_CONNECT_LEVEL sections. This gives you the ability to combine
certain pages of panels or to combine panels under certain conditions. In Axcess, once the panels were
combined you were locked into that system configuration.
Instead of writing the following statements:
PUSH[MSP1, 1]
PUSH[MSP2, 1]
PUSH[MSP3, 1]
[RELAY, 1] = ![RELAY, 1]
[MSP1, 1] = [RELAY, 1]
[MSP2, 1] = [RELAY, 1]
[MSP3, 1] = [RELAY, 1]
You can use device sets or channel sets to accomplish the same functionality:
